For the second time in as many months, razor blades were found embedded in the grass near a children’s playground at Mission Bay Park near Bonita Cove.

Police officer James Johnson with Crime Stoppers said razor blades were found at the park on Aug. 10 and, most recently, on Sept. 5.

No one was injured the second time but a woman cut her foot slightly the first time blades were found in August, Johnson said.

“They (razor blades) were 1 to 1 1/2 inches long, something somebody would use in a cutting or scraping tool for a window,” he said. “They were definitely placed there intentionally in the grass area surrounding a children’s playground. It looks as if the two events could be linked, but we have nothing yet to say they are for sure.”

In August, Johnson said a woman stepped on a razor blade in the park and got “a very minor cut.” This last time, someone called police at 6:18 p.m. to report razor blades had been found in the park.

“People who discovered the blades stood in a group waiting for police to arrive,” Johnson said, adding officers did a sweep of the area with a metal detector. “It’s certainly safe now.”

Detectives are investigating both incidents with the cooperation of the Park and Recreation Department.

Anyone with information on either incident is urged to call San Diego Police Northern Division at (858) 552-1700 or Crime Stoppers anonymously at (888) 580-8477.

Coach charged in PB cocaine arrest

A high school seasonal baseball coach awaits a Sept. 23 preliminary hearing on charges he was in possession of cocaine during a July 4 incident in Pacific Beach when he was arrested.

Jackson Lawrence Chapelone, 29, of Carlsbad, has pleaded not guilty to the charges, which also include resisting an executive officer with San Diego police in the 3 a.m. incident at Bayard and Hornblend streets.

Chapelone has posted $5,000 bond and remains free. The cocaine charge is a felony. Other charges that were initially reported were hit and run and trying to dissuade a witness, but those were not filed by the District Attorney’s office in San Diego Superior Court.

He was a temporary employee at La Costa Canyon High in Carlsbad in the spring. He played baseball at Cal State San Marcos and Bonita Vista High School when he was a student there respectively, according to school websites.
